* WARNING: The following may contain information that some readers may not want to know about the new season of “The X-Files” before it airs.

THIS fall on “The X-Files,” FBI agent Dana Scully is pregnant – and her missing partner, Fox Mulder, could be the daddy.

Though Mulder (David Duchovny) will be back, Scully (Gillian Anderson) will have a new partner – John Doggett (Robert Patrick from “The Sopranos”) – because Mulder was presumably abducted by aliens at the end of last season.

Also in the final moments of last season’s finale, Scully dropped her bombshell – she’s pregnant despite popular “X-Files” lore that says she’s supposed to be barren.

Chris Carter, the show’s executive producer, tells this week’s edition of Entertainment Weekly that its a “hypothetical” possibility that the baby belongs to Mulder.

“These are two people who have maintained a very powerful and respectful relationship,” Carter says.

“But like all relationships between men and women, sometimes feelings are expressed in a physical way. I don’t think it would be dishonest for them to have done that.”

Carter says he’s aware that the unfulfilled sexual tension between Mulder and Scully has been a talking point among the show’s fans for years. However, “I’ve always said nothing is impossible on ‘The X-Files’ and anything is possible on ‘The X-Files.”

“I have confidence and possibly inner knowledge, that the fans will get to see how Scully got pregnant – before Christmas,” Anderson says.

Meanwhile, the very fact that there is a new season for “The X-Files” is something of an unexplained phenemenon.

Until late last spring it was not known if Duchovny would be back to play Mulder or if Carter would renew his contract.

As it stands now, Duchovny will appear in only 11 episodes and Carter will stay on as the show’s honcho.

Duchovny’s new deal was inked the day before Fox announced its new fall schedule last May and was tied to a legal settlement with the studio of the star’s lawsuit.

Duchovny sued Fox and Carter because he felt “X-Files” repeats had been sold to Fox’s cable network FX at bargain basement prices.
